Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sinter composition and a mixture, and more particularly to a sinter composition and a mixture that contribute to the growth and activation of plants and animals.

[0002]

2. Description of the Related Art In recent years, so-called ceramics, which are sintered products of metals and non-metals, have various functions and have been studied in various fields. The present inventor is conducting research on the biological activation effect as part of the development of new functions of such ceramics. The biological activation of ceramics itself cannot be evaluated directly, but usually, a liquid such as water or a gas such as air is brought into contact with ceramics to give the liquid or gas after treatment to living things,
It can be evaluated by observing the degree of growth of the organism.

There is also a direct evaluation. For example, far infrared rays are known to be useful for the growth of plants and animals with electromagnetic waves of 4 to 50 microns, and the wavelength range of far infrared rays particularly useful for the growth of plants and animals is known to be in the range of 4 to 16 microns. Therefore, by measuring the emissivity of such far infrared rays, it becomes possible to directly evaluate the bioactivation of ceramics.

Conventionally, Japanese Patent Application Laid-Open No. 5-13809 discloses that
A technique is disclosed in which a fired product having a characteristic that the far infrared ray having a wavelength of 8 to 14 microns has an emissivity of about 90% is effective for the growth of organisms.

[0005]

However, JP-A-5-1 is used.
In the burned material described in Japanese Patent No. 3809, since the emissivity of far infrared rays having a wavelength of 4 to 8 microns is low, the growth and activation of animals and plants were insufficient and there was room for improvement. Further, it is known that manganese emits far infrared rays, but since the above-mentioned conventional fired product must contain such manganese,
There is a drawback that the selection range of raw materials is limited, and therefore development of ceramics substantially free of manganese is desired.

Therefore, the present invention has a high emissivity of far-infrared rays having a wavelength of 4 to 8 μm even if it is a sintered composition or mixture containing substantially no manganese, and contributes to the growth and activation effect of animals and plants. It is intended to provide sintering compositions and mixtures.
